, a and State of New York, haveinvented certain new i and useful Improvements in Windowrflperating Devices, of which the following is a specification, such as will enable those 'skilled in the art to which 10 it appertai'ns to make and use ,thegsame.

This invention relates to window operating devices, and particularly to devices oftthis class designed for raising and lowerin the windows or window anelsfiof motor 1e ve icles, and the object of 't einvention is tmprovide anonel lever and counterbalanced construction, by means of which the window and positively raised panels may be e'asil and lowered ;',a,if.urt or object being toprozo vide a device of the class specified of unitary construction to facilitate its mounting in connection with a suitable support; and with theseand other objects in view, the invention consists in a device of the class and s ecified, which is siinple in construction, e cientqln use and which is constructed as hereinafter describedand claimed. i

The invention described andclaimed hereto in is an improvement on that shown and January 30,1922, Ser.

sides pf said panel," tracks or rnnwafys 10 in which roller bearings 11 mounted on a the free ends of levers. 12 are movable, The other ends of the levers 12 are mounted in.

'acommon pivot 13 secured'to an attach 6h plate 14 and adjacent to thepivoted en the levers are provided with elongated apertures15 in whichfpins 16 are movableand the pins 16 are secured to a slide 17 mounted ,to move vertically on.the attaching "plate 14 and the upper end thereof bein provided with a threaded block 18, throng which a screw shaft 19 passes.- A rod 20 is mounted .Iin gonnection with the, attaching plate 14 and mounted thereon is a spiral compression We spring 21 whichtis ada ted to coope 1w with a spring seat 22 ont e slide 17.

The n per end. of the attaching plate 14 is en arged and provided with a cup shaped housing 23 in which is mounted a pin 24, on which is rotatably mounted a bevel gear 25, which meshes with a pinion V 26 on the screw shaft 19, and the gear is provided with an angular extension 27 wh ch passes into a correspondingaperture in a crank 28. A oke' 29 is mounted on the pin 24 within t e housing 23 and into which the upper end of the screw shaft 12 passes, and which forms a port for said shaft.

proved o crating device as shown in full lines 1n ig. 1 of the drawing, the window pa nel'fi is in fully open position aridwhen 7 'it.isdesired to raise or close said win ow panel, thecrank 28I-is 'rotated in the proper direction and the levers 12 are first moved outwardly,'and,then inwardly in'the tracks or runways 10, and th sp'ring21 will operate to balance said window panel, the samei,

, garded as a dead center position, when said zontal position;

bearing and supf '1 H r I lication, filed Tn the position of the parts of my ims-Jo in anhoriwindow panel is movable. The window" lt will be apparent that myiimprovement paneljd isfprovided at its lower edge with isdesigned particularly for use 1n raising a metallicstrip 9 carrying at its opposite comparatively wide window panels, such as the panels employed in connection with the described, said device being of unitary conbody structure of a motor vehicle or the struction and comprising an attaching plate, like, and while I have shown certain details a bevel gear rotatably mounted in connecof construction for carrying myinvention tion with said plate, means for rotating said into eflect it will be understood that I am gear, a screw shaft adapted to be'rotated not necessarily limited to these details and by said gear, a slide in'threadede agement various changes therein and modifications with said screw shaft and actua thereby, thereof may be made *within the scope of laterally disposed levers pivoted to said atthe appended claims without departing from tacl'iing plate and: provided adjacent to the thespirit of my invention or sacrificing its pivoted ends thereof with elongated aper- 75 advantages.
